T 0 all whom t may concern Be it known that I, FRANCIS L. BAIN, acitizen of the United States, yresiding at Everett, in the county ofMiddlesex and State of Massachusetts, have invented new and usefulImprovements in Desk and Chair lom-biuations, of which the following isa specification.

This invention relates to school furniture and more particularly tocombined chair and desk mountings.

The principal object of the invention is to provide a unitary structurewhich is simple. cheaply constructed, durable and etlicient and whichembodies novel features of adjustment and support for the variousvparts.

Further objects of the invention will appear as the following specificdescription is read in vconnection with the accompanying drawing whichforms a part of this application, and in which Figure 1 is a sideelevation. Fig. 2 is a vertical sectional view. Fig. 3 is a horizontalsection vshowing in bottom plan view the seat and desk casting.

Referring more particularly to the vdrawing. 1 represents a base whichis substantially H-.shaped in plan and which is Drovided adjacentopposite ends with raised bosses 2 and 3 centrally recessed or aperturedas shown at 4 and 5 to receive the seat and desk standards 6 and 7respectively. Each of these standards is tubular and has slidabl'vmounted therein an extension standard 8 upon which is adjustably mountedan inverted cup-shaped collar 9 held in position by a set screw 10 andsurrounding the main standard 6 or 7 with an interposed metallic washer11 preferably of lead, babbitt or other similar material. The lower edgeof the cup fits in an annular recess 12 for-med in :1 cup-shaped collar13 adjustably secured upon the main tubular standard 6 or 7 by a setscrew 14.. The upper end of the eXtenson standard 8 for the desk hassecured thereto a spider-like casting 15 secured to the underneath sideof the seat 16 while the extension 8 of the desk standard has securedthereto crescent-shaped casting 17 which 1s bolted to the underneathside of the desk 18. The castings 15 and 17 may be secured on therespective extensions by a set screw 19 or may be formed as an integralpart thereof` if desired. As shown, the lower edge of the cup-shapedcollar 9 rests upon a washer 20 which is interposed between the loweredge of the cup and the base of the recess 12. The extension standard 8therefore v has a two-point support, z'. e. upon the upper end of thetubular standard 6 or 7 and upon the cup collar 13. Also the extensionis laterally braced by reason of the overhang of the collar 9 engagingthe side walls ofv the standards 6 or 7.

The standards 6 and 7 may be secured within the sockets 4 and 5 in anysuitable manner such as by shrinking or sweating and the parts mayassume any desired dimension or be of any suitable material withoutdeparting from the spirit or scope ofthe invention.
